The air conditioner did not work. I contacted the host to get it fixed. The host said it was fixed and when I returned around 10pm the air conditioner still did not work. Because the room is on the 5th floor with no fan and it was a hot day in Bangkok, we did not ended up leaving and getting a room elsewhere.
Also note, the room did not have toilet paper. This may have been a mistake but I did not ask because of the air conditioning situation.
